Question

solve:
radius = 12 cm ,
diameter = ?,
circumference = ?

Answer 1

Answer:

d=r×2

d=12×2

d=24

c=2πr

c=2×3.14×12

c=3.14×24

c=75.36

give thanks to my answer

Answer 2

Answer :-

• Diameter = 24 cm
• Circumference = 75.4 cm ≈

Step-by-step explanation :-

To Find,

• The diameter
• The circumference

Solution,

Given that,

• Radius of the circle = 12cm

As we know that,

Diameter = 2 × Radius, therefore

➮ Diameter = ( 2 × 12 ) cm

➮ Diameter = 24 cm ★

Hence, the diameter of circle is 24 cm.

As we know that,

Circumference = 2πr, therefore

➮ 2 × 22/7 × 12

➮ { 2 × 22 × 12 } / 7

➮ { 44 × 12 } / 7

➮ 528 / 7

➮ 75.4 ≈ ★

Hence, the circumference of the circle is 75.4cm ≈.
